Abstract

Ce relais (100) comprend une palette flexible en forme de L (201) dont l'extrémité supérieure est courbée sur ces deux côtés, de façon à former un dispositif d'arrêt (201a), lequel entre en prise avec un bord (204c) de l'extrémité supérieure (204a) d'un noyau (204). Un élément élastique (205c) d'un ressort à charnière (205) supporte la palette flexible (201) de manière que celle-ci puisse osciller. La périphérie de l'extrémité supérieure de la palette flexible (201), lorsqu'elle est attirée magnétiquement, entre en contact intime avec l'extrémité supérieure (204a) du noyau (201).
